Errr, I acked based on what I saw and immediately afterwards found that
this does not apply cleanly to 2.6.25-rc8-mm1 due to whitespace damage.
Here is a whitespace-undamaged version

patch against: 2.6.25-rc8-mm1
in a5d76b54a3f3a40385d7f76069a2feac9f1bad63 (memory unplug: page
isolation by KAMEZAWA Hiroyuki), "isolate" migratetype added.
but unfortunately, it doesn't treat /proc/pagetypeinfo display logic.
this patch add "Isolate" to pagetype name field.
